Difference Between Leading Strand & Lagging Strand of DNA

WebAug 10, 2024 · Answer: Primase is a DNA dependent RNA polymerase. It adds RNA primer to the DNA strand and lay the foundation of DNA replication. It is important because DNA polymerase can add nucleotides to the 3'- end of the strand. Primase, in the form of RNA primers provide free 3'- end to the DNA polymerase and thus, help in initiating DNA … WebAnswer (1 of 5): You may’ve learned that DNA polymerases can’t ‘jumpstart’ a new strand on their own—they can only ADD TO an existing strand.
